 Marlin 3D Printer Firmware
 ==========================
+[![Coverity Scan Build Status](https://scan.coverity.com/projects/2224/badge.svg)](https://scan.coverity.com/projects/2224)
+
 Marlin has a GPL license because I believe in open development.
 Please do not use this code in products (3D printers, CNC etc) that are closed source or are crippled by a patent.
